Abstract
The invention relates to a wound plaster by applying a negative pressure sucking device to fix wounds after surgery and the like. The wound plaster consists of a wound plaster surface, a negative pressure air chamber, a one-way air valve and an air sucking opening. The wound plaster surface is fixed on the wound. The air is pumped out by a sterilized syringe connecting the air sucking opening until the wound plaster surface is tightly attached to the skin around the wound. The negative pressure air chamber is collapsed, and the high negative pressure state is maintained. The one-way air valve is closed to block the air reflux. Double circular sucking grooves and distributed millimeter sucking discs at the bottom are connected with the negative pressure air chamber by capillary channels. The wound plaster can be firmly sucked and fixed on the wound and the surrounding skin by the double circular sucking grooves and the millimeter sucking discs. The wound plaster provides good condition for wound curing and can replace part of traditional postoperative needles and threads sewing. The wound plaster can suck the wound exudate.
Description
Affiliated technical field
Relate to a kind of bandage, apply to the cleaning wound behind the medical operating, can partly substitute a kind of medical supplies that traditional postoperative needlework are sewed up.Patent utilization negative-pressure adsorption device of the present invention fixes the smooth wound of postoperative cleaning, reduces postoperative scar and forms, and promotes wound healing.Patent of the present invention also has the function of absorbing wound fluid.
Background technology
At present, known traditional surgery adopts needlework suture operation otch, often stays the stitching cicatrix of " Scolopendra " shape behind the wound healing, influences the operative site skin beauty greatly.How to handle wound fluid in addition and also be wherein hang-up.
Summary of the invention
Influence this problem of operative site skin beauty in order to overcome the stitching cicatrix that stays " Scolopendra " shape after existing surgical postoperative conventional needle suturing with thread management operative incision heals, patent utilization vacuum suction principle of the present invention is made negative-pressure wound plaster, can fixedly secure surgical wound, part substitutes traditional postoperative wound and sews up, reduce the area and the size of cicatrix, promote wound healing.The drawing liquid of patent of the present invention and vacuum suction function can be used for absorbing the transudate of wound.
Patent of the present invention solves the technical scheme that its technical problem adopts:
The present invention mainly is made up of wound binding face and negative pressure chamber device two parts, product is mainly made by the transparent medical polymer material, transparent material is to observe the wound healing situation for convenience, binding face is by having the viscous force coating that the antibacterial-anti-inflammatory drug nano material constitutes, it can make wound binding face and skin good combination, and prevent wound infection, dual annular bothrium in bottom and the millimeter sucker that gathers are connected with high-tension negative pressure chamber device by capillary tube, the negative pressure chamber device forms the height negative pressure state after the connection asepsis injector deflates, dual annular bothrium and the millimeter sucker that gathers can fixedly secure and airtight firmly wound and surrounding skin thereof, for wound healing creates favorable conditions.The negative pressure chamber device partly has valve structure, stops gas backstreaming, and the negative pressure chamber device can be with wound fluid negative suction gas cell device, and keeps veneer suction with negative pressure.Another QI KOU cecum is cut off with shears finishing using, and healing is pasted take off smoothly.
The beneficial effect of patent of the present invention is,
Can fixedly secure surgical wound, part substitutes traditional postoperative wound and sews up, and reduces the area and the size of cicatrix.Patent of the present invention has the function of the transudate of absorbing wound.

Wherein code represent 1 respectively, QI KOU cecum 2, bleeding point 3, valve structure 4, Non-return air valve 5, negative pressure chamber device 6, capillary channel 7, wound binding face 8, viscous force coating 9, anti-gummed paper 10, dual annular bothrium 11, millimeter sucker 12, the asepsis injector be stained with
The specific embodiment
Product is by wound binding face (7), negative pressure chamber device (5) Non-return air valve (4), bleeding point (2) is formed, product is mainly made by the transparent medical polymer material, can observe the wound healing situation at any time, wound binding face (7) surface is to constitute viscous force coating (8) by containing the anti-inflammation drugs nano anti-biotic material, can make wound binding face (7) and wound and surrounding skin good combination thereof, negative pressure chamber device (5) is connected by capillary channel (6) with a dual annular bothrium in bottom (10) and a densely covered millimeter sucker (11), dual annular bothrium in bottom (10) and the millimeter sucker (11) that gathers can paste healing and fixedly secure in wound circumference, can stop pathogen to enter wound by airtight wound.Negative pressure chamber device one end is Non-return air valve (4), valve structure (3) can stop gas backstreaming at the negative pressure closure state, the top of negative pressure chamber device (5) has very strong back stretch, can keep negative pressure chamber device (5) inner height negative pressure, and wound fluid negative suction gas cell device (5) can be extracted out transudate with asepsis injector (12).QI KOU cecum (1) is cut off with shears finishing using, and negative-pressure wound plaster is taken off smoothly.
Clean wound before using earlier and keep wound surrounding skin drying, choose the product that is fit to the otch specification, from preventing that being stained with gummed paper (9) takes bandage off, prolongs with hands and vertically tightens surgical wound, be attached on the wound negative-pressure wound plaster is smooth, and guarantee that bandage and wound and surrounding skin thereof combine closely.Connecting bleeding point (2) with asepsis injector (12) extracts gas out, be close to the wound surrounding skin until veneer, top negative pressure chamber device (5) subsides and keeps height and can pull out asepsis injector (12) during negative pressure state, the back valve structure (3) of bleeding is closed to stop gas backstreaming (failing neat fit or the top air chamber can't be kept the negative-pressure wound plaster that negative pressure should renew as wound surface), keep close observation, as find to have in the air chamber transudate in time to extract out, and keep negative pressure chamber device (5) height negative pressure state.Use and cut off QI KOU cecum (1) with shears after 3-5 days and negative-pressure wound plaster can be removed, the negative-pressure wound plaster that more renews behind the clean wound is until wound healing.And guarantee that wound is not drawn back by external force.
Application notice: 1. use this product to need in strict accordance with surgery sterile working program.2. must clean wound surface before using, avoid the water contact in the use, please don't catch after the opening and touch the middle medicine heart.3. the skin allergy person stops using.4. to this product allergy sufferers forbidding, the careful usefulness of allergic constitution person.5. when this product character changes or when gas leakage packing ban use of.6. non-cleaning wound must not use.
